The British Retail Consortium said other retailers are imposing similar limits. Richard Dodd, a spokesman for the trade association, said that stores and manufacturers across the country have been watching the trend for several months, and individual stores have been imposing their own rations for some weeks now.
Danone, which sells Irish-made baby formula in the U.K., said it does not export these products elsewhere. It does, however, sell some of its other dairy brands in China, and the company is increasing those supplies as well to meet demand there.
